ATI graphics major problemo. Nvidia is vice versa but still a problemo..

I didn't say the ATI hardware suks but the the graphics are very not so realistic in rendering. Color too strong and still jaggy despite having to turn it to the max. However Nvidia is vice versa, its graphics are very much realistic in rendering and color but the hardware are very fragile to heat and overloaded GPU/RAM. Throughout my entire life i have my first respect to ATI graphics in the late 90's when DX7 was very much hardware utilized for soft render without TNL. Then came NVIDIA TNT with TnL with more life like graphics. Until present day i've burned 6 pieces of NVIDIA graphic cards just because of rendering my 3d works, i did not even Over Clock for gaming yet...actually i hardly play any games. However no hardware failure problem for ATI just the poor graphics i have to live with it. My last project rendered with Nvidia was "EXAGE" models, everything before it also have smooth render and in game looks..perfect Anti-aliasing. "XAVAGE" project was on ATI hardware....yes you can see all the rendering and screenshots isn't on par with Nvidia render as you can compare from several screen shot from my projects. ouch!
However I would thank to ATI today because the still making AGP slot support for older pc which is now i'm survive because of it. If i'm loaded with huge budget i'll get back to Nvidia

GPU R.I.P my friend.

Well looks like all my PC at home over worked especially the GPU cards.
-GEFORCE 7600 GS (overheated and died due extensive heavy poly rendering on development models)
-VANTA LT (one of the resistor burned out casing the AGP slots unable to control the current supply to GPU)
Both replace with this new AGP cards to revive old but worth working and investment.
-ATI X1550 PRO
-GEFORCE FX5500
yeah, yeah i know they both have cheap performance but as long it does the job they are worth running. Heck save money than buying new PC.
Btw the old GEFORCE 7600 GS worth the living before it died since it already worked lots of project and stuff interm of Return Of Investment (ROI).
Below are the page links show differences between and old gpu with replacement ones:

It looks like i loose a few millions of render performance by a seconds but heck its a value card nearest to 7600GS with same memory bandwith and advantage of +50Mhz extra core clock.
Well atleast i can run my PC and view stuff on internet via my monitor,

I've fried my PC!!!

OMG!! the overheat kills it, whole GPU, display card memory and bridge chipset are totalled. There's goes my work on 3d models and track project. All delayed by clogged dust which blocked the fan from cooling of the heat sink. Its all about $$$ getting it fix. Maybe i just lay back, sit back and relax...should jump on my bike and play my r/c models to get over it until i get my budget for new work station computer for 3d model work. Ahhh...dammit.

Oh well i have nothing to lose because the investment on these hardware was worth it since the return of investment was big enough before it break down. With total of 17 3d models for games have been created, 7 graphic project and 40 publishing thats really a lot done by this PC. I'll try to get it fixed even though it uses old AGP slot which very hard to find. Wish me luck.
